NO. 2281. A REVISION OF CHALCID-FLIE8— PHILLIPS AND EMERY. 457 



Propodeiim without groove and rugose. 



Petiole about one-half the length of hind coxae and with low rugae. 



Legs : Femora black, except at knees ; tibia dusky ; knees testaceous. 



Antennae : Flagellum with pedicel shorter than head and thorax 

 combined ; scape as seen in lateral profile about same width through- 

 out and same width as first flagellar joint; very slight shoulder dis- 

 tally ; scape, exclusive of base, one-fifth as broad as long. 



Redescribed from many females reared in cages under artificial 

 conditions, and from specimens reared from galls in rj^e stubble col- 

 lected at Warsaw and La Fayette, Indiana, and from the types in the 

 United States National Museum. 



This species makes conspicuous hardened enlargements of galls 

 usually in the second or third internodes from the base of the plant. 

 It breeds only in rye and is normally thelyotokous. Males very rarely 

 occur. 



HARMOLITA HESPERUS, new species. 



Plate 40, fig. 4 ; plate 44, fig. 5 ; plate 46, fig. 15 ; plate 47, fig. 3. 



Female. — Length 3.75 mm. Praescutum rugulose. Pronotal spots 

 large, occupying two-thirds or more of anterior dorsal margin of 

 prothorax. 



Propodeum with a narrow, deep, median, longitudinal groove; mar- 

 ginal carinae very often interrupted and irregular, and there are 

 numerous cross rugae within the groove ; area laterad of groove very 

 rugose. Fimbria very inconspicuous. 



Abdomen distinctly longer than head and thorax combined; seg- 

 ment 2 from one-fifth to one-fourth the length of the abdomen exclu- 

 sive of 1 ; 3 shortest, 5 longest ; 4 and 7 subequal ; G usually longer than 

 either 4 or 7. 



Legs: Front femora, distal two-thirds of middle and one-half of 

 hind femora, and all tibiae translucent reddish-brown ; basal part of 

 middle and hind femora fuscous. 



Antennae: First funicle plus ring-joint distinctly longer than 

 pedicel; none of funicle or club joints quadrate; club joints same 

 width as fifth funicle; scape dusky to black. 



Species medium to very large in size. 



Male (pi. 47, fig. 3). — Length 2.5 mm. Praescutum same as in 

 female. Pronotal spots occupying one-third to one-half anterior 

 dorsal margin of prothorax and are often obscure. 



Propodeal groove deep and usually well defined throughout. Pro- 

 podeimi very rugose. 



Petiole about same length as hind coxae; finely rugose to granu- 

 lose. 



Legs: Front legs, tibiae, distal two-thirds of middle femora and 

 sometimes apical one-third of hind femora reddish-brown; occasion-
